Q: Why propranolol is a preferred Beta-blocker in thyroid storm?
Answer: Propranolol is a preferred Beta-blocker in thyroid storm because it inhibits the type 1 deiodinase, which may help reduce serum T3 level, besides treating the symptoms. Also, it can be given orally, via nasogastric route or intravenous.
